The postoperative therapy protocols after tendon transfer procedures are not well defined, inconsistently applied, and lack evidence for their effectiveness. The study proposed here will investigate cortical change to assess outcome dependent plasticity. Thus, it may be possible to predict why some individuals do not re-train the transferred muscle as well as others. Establishing this relationship can lead to understanding the mechanisms of successful interventions and may identify brain based dynamics that could become the focus of future treatments (e.g. biofeedback, brain stimulation, etc.).
